Re - structuring android project files in Android Studio

Question

Since my application is growing more and more dense each day. I thought of re-structuring various files.

By re-structuring, I mean to add folders seperately for screen activites, another folder for dialog xmls, screen xmls, for custom adapters, etc. In other words, I need to segregate files according to their significance.

Currently, all my java files are listed in src folder (screen activities, custom adapters, business logic, etc.) and all the xmls (screens, custom list view design, custom dialogs, etc.) are present in layout folder.

Is it feasible? What impact will it have on the existing project?

Answer 1

Folders are synonymous with packages -- that's how the IDE interprets them. So putting them in separate folders actually creates separate packages. That's the downside, they won't have the same scope/permissions as if they were in the same package.

Answer 2

Packages in Java

What you're talking about is most likely packages.

Packages makes structuring of bigger projects and navigating through it much easier.

However you can't without writing your own gradle extension put your XML files outside /res/ folder, but codewise, wrapping your classes in packages makes working in bigger codebase much easier

You define the package you class is in before defining the imports in following way:

package com.ruuhkis.test;

import android.content.Context;

class Test {
}

then the Test class is put in folder /src/com/ruuhkis/test/ folder to be found by the compiler
